IMPROVEMENT IN TRUSSES.

The Schedule referred to inthese Letters Pat-ent and makmg part of the same.

Td all whom `it may concern .i

Be it known that I, PETER MLLER, of Middle Lancaster, in the county of Butler and State of Pennsyl-V vania, have invented an improved Truss; and I do hereby declare ythat the following is a full and exact description thereof, reference being had to't-he'accompanying drawings making part of this specilioat-ion,

Figure l being a section of the pad and pad-holder,

' and showing the spring or bow beyond.

Figure 2 a View of the truss, in perspective, showing a portion of -the spring uncovered.

Like letters designate corresponding parts in both figures.

Let A represent the bow or spring, B the adjustable pad-holder, and C the lpad of the truss.

First, the pad-holder B is adjustable on the end of the bow or spring A, the neck a of the holder terminating in a clasp, g, which slides outhe springa1 1 dis held by a'rivet or screw, b, fitting in one of a set of holes, h 1i, in the spring. This adjustment allows the enlargementor contraction of the size of the truss, and enables the pad to be brought into exact position over the rupture. a

Second, the neck a of the pad-holder B is curved outward so as to bring the pad-holder away fromcoutact with the body, and allowthe adjacent end of the spring to tit the body.-

Third, the pad-holder B has an entire ratchet-wheel, c, and a spring detent, d, secured to the holder-plate j, which may turn to any angle around the n eck pivot.

Fourth, the pad C is made of wood, and has a socket,

i, lined with metal, which turns around the swivel-ball k, The material, wood, gives Aa tirm pressure, is not liable to absorb oiensive odors, and is light, and does not conduct away heat Vtoo rapidly.

The construction and arrangement of the parts above described produce a perfectly-fitting truss, easy to wear, adjustable to any position of hernia, and to the' desired' degree of pressure,and keep the truss well up on the body without the assistance of straps.

My invention consists in making the spring A of :1

strip ot' steel, Z, iu the center, and side strips m m oi iron, the strips being welded together under the harnmer, and the steel properly tempered. This combination of steel and iron to form the spring is important and .valuable It enables the wearer to adjust the spring to any bend he may desire, and the iron will keep it in any. shape into which it is bent, while -the steel will continue to exert the requisite elasticity.

.'lhus, the spring may be adapted to persons of different'sizes, or to thesame person when fat.v or lean,

and it enables himto fit the spring exactly to his form.

The strips of steeland iron are not necessarily arranged just as shownany equivalent construction y may be adopted.

I claim as my invention- Therstrips lof steel, and lm-of iron, substantially as 'and for t-hepurpose hereiuspeciied; l

The specification of my improved truss signed by,

me this 22d day of May, 1869.
